Braves vice chairman John Schuerholz watches as a steel beam is installed during a "topping out" ceremony at SunTrust Park Monday, June 13, 2016, in Cobb County. In keeping with construction industry tradition, a ceremony is held to mark the installation of the highest or last piece of steel placed on the construction project. Tradition also calls for a tree to be placed atop the beam to appease the tree-dwelling spirits displaced during construction.
